Description
Technical field
The utility model relates to heating ventilation and air-conditioning field wind speed proving installation, is specifically related to a kind of hot-wire anemometer multi-point sampler device that has USB interface.
Background technology
The toilet is most important, the most representative measure that the air cleaning technology is created clean microenvironment.The appearance of way flow toilet makes the air cleaning technology that leap take place, and makes the environment of creating high-end cleaning become possibility.The way flow toilet is as the principal mode of electronics, medicine and biological industry, occupies more and more important position with the development of these industries in clean field.The face wind speed (air quantity) of toilet and unevenness have material impact to the environment of high-end toilet, in order to control the environment of toilet better, improve its cleanliness factor, then need opposite wind speed and unevenness accurately to test and analyze.
At present, the method of testing that adopts in way flow toilet high efficiency particulate air filter wind speed field tests mainly contains two kinds both at home and abroad: a kind of is the pointwise test method, the directly hand-held anemoscope of people, stand in the filtrator below and carry out pointwise test, need people record data aside in addition according to the point position that arranges; Another kind is present more advanced in the world multi-point test method, and a plurality of anemoscopes are installed on the measuring staff, and are connected with digital display instrument, and the hand-held measuring staff of people stands in the high efficiency particulate air filter below and tests, and once can carry out multi-point sampler.
Above-mentioned two kinds of method of testings all are that the directly hand-held anemoscope of people stands under the high efficiency particulate air filter and tests, on the one hand, because the shake of staff then can produce certain influence to test result; On the other hand, human body to the stopping of wind speed, can cause certain error to test result, moreover these two kinds of method of testings is also bigger to the consumption of human body physical agility to a certain extent.Simultaneously for above-mentioned two kinds of method of testings, the former can only average as the face wind speed by pointwise test, has tangible asynchronism, the precision and the accuracy of test result are lower, this in addition method of testing requires two people to cooperate, testing efficiency is low, and the test job amount is big, and on-the-spot test, follow-up data Treatment Analysis and report to finish required time long; The latter then can only the display surface wind speed, can not show each point wind speed, air quantity and unevenness.
The utility model content
The purpose of this utility model provides a kind of hot-wire anemometer multi-point sampler device that has USB interface, overcome asynchronism in the existing high efficiency particulate air filter wind speed proving installation test process, testing efficiency is low, and measuring accuracy is low, and the test job amount reaches personnel greatly and disturbs drawbacks such as strong.
Thinking of the present utility model is: 1. adopt adjustable cross bar of level and vertical position and A-frame, can realize that not only point position adjusts by the difference requirement, and guarantee static test and the interference of avoiding personnel.2. at a high efficiency particulate air filter, adopt the disposable method of finishing test of multiple spot, guaranteed the synchronism of test, improved measuring accuracy, less greatly workload.3. adopt digital display mode,, can directly each point wind speed, face wind speed, air quantity and unevenness be presented on the screen according to the processing and the analysis of the rate signal of gathering by micro computer.4. this device can be dismantled and assemble flexibly, is easy to carry.
The hot-wire anemometer multi-point sampler device that has USB interface, it is characterized in that: the top of A-frame is connected with a pair of " V " shape support bar, " V " shape support bar connects with a pair of corresponding frame of testing jig, be connected with cross bar in the testing jig frame, the hot-wire anemometer of one group of self-carried USB interface is installed on the cross bar, directly links to each other with micro computer with data line by the USB converter.
Described testing jig is provided with slideway in its corresponding frame, and the two ends of cross bar are connected with slideway by ball; The hot-wire anemometer level and the vertical position of self-carried USB interface can be adjusted.
Measuring wind scope of the present utility model is 0.05～5m/s, measuring accuracy :≤3%, and number of test points: optional.
The hot-wire anemometer that has USB interface is installed on level and the adjustable cross bar of vertical position, not only can adjust point position according to tested object, and has guaranteed the synchronism and the accuracy of test, has also avoided personnel's excessive interference simultaneously.
The hot-wire anemometer that has USB interface directly links to each other with micro computer with data line by the USB converter, can realize on-the-spot reading, and whether judged result is qualified automatically.
The utility model wind speed testing element adopts the hot-wire anemometer of a plurality of self-carried USB interfaces, can realize that multiple spot tests simultaneously, possesses the synchronism of test; Cross bar that employing level and vertical position are adjustable and tripod can realize that point position adjusts by the difference requirement, and test process can be avoided personnel's excessive interference; Adopt digital display mode, can directly show each point wind speed, face wind speed, air quantity and unevenness, realize on-the-spot reading.Than other similar proving installations have the measuring accuracy height, accurately, convenient advantage such as quick, this device also can be used for the test of air port wind speed and air quantity simultaneously, in engineering practice, have very strong realistic meaning, to the heating ventilation and air-conditioning field particularly the development of toilet's measuring technology very big facilitation is arranged.
